hi, I have two C# Compact Framework applications. I want to make Interprocess communication between the applications by Message Window. Does any one know how to do it
I using MarshalEx.StringToHGlobalUni(message); to convert the message into IntPtr and pass this IntPtr and unmarshal it in the otherside by calling Marshal.PtrToStringUni(wParam); to unmarshal the int pointer back to string. However this doesn't work. Since these two applications are not sharing the same memory pool. Any one know how to resolve this
Or if MessageWindow is not a proper way to do it, what are other choices out there
Please Help, Great Appreciate. Thanks

Regardless, Wayne
 
The MarshalEx.StringToHGlobalUni is using LocalAlloc call behind the sceen
which will work inside of one process only. For interprocess you'd better
off by using WM_COPYDATA message.

hi, Alex: Thanks for the information. I finally get it working. I can send string and read it in the other end
However, I am running my applications in IPAQ. Whenever I send the string, "Hello". IPAQ popup a window ask Data "Hello" Received. Do you want to receive it? "YES"/"NO". Do you know how to avoid this popup window code wise or
from the IPAQ setting?

Thanks for you information, help me a lot

Could you show the code you're using?

I don't see anything wrong with the code.

Which IPAQ is that? What OS it is running?
